The Norton Utilities releases are collections of software utilities.
Peter Norton published the first version for DOS, The Norton Utilities, Release 1, ca 1981. Release 2 came out several years later, subsequent to the first hard drives for the IBM PC line. Peter Norton's company was sold to Symantec in 1990. However his name remains as a "brand" for Symantec's range of utility and security software for home users.

Disk tools included with this release are not compatible with FAT32.
The Windows version of 'Speed Disk' works with much greater speed than Microsoft's supplied defrag program, as it moved groups of clusters, not single clusters as Microsoft's Windows Disk Defragmenter. Changes in the way Windows operates meant that many of the old utilities were either dropped completely or replaced with GUI based versions. However, with the advent of Windows XP onwards, Norton's 'Speed Disk' reverted back to single-cluster defragmentation.
